IMPROVEMENT IN BUCKBOARD-WAGONS.

Specification forming part of Letters Patent No. 214,160, dated April 8,187 9; application filed September 6, 1878.

To all whom it may concern:

Be it known that 1, CHARLES D. L GRAND, of Wilkesbarre, Luzerne county,Pennsylvania, have invented anew and useful Im provementinBuckboard-Wagons, of which the following is a specification.

The object of my invention is to so construct a buckboard-wagon as toimpart to the longitudinal bars of the frame thenecessary strength andstiffness without materially detracting from the elasticity of the frameas a wholean object which I attain in the following manner, referencebeing had to the accompanying drawings, in which- Figure 1 is aperspective View of my improved frame for buekboard-wagons; Fig. 2, aside view of the same; and Fig. 3, an enlarged view, partly in section,of a portion of the frame.

A is the front axle, and B the rear axle, of the vehicle; and D D, theusual longitudinal bars, connected by transverse strips E E, upon whichrests the body of the wagon. (Not shown in the drawings.)

The bars D D rest at the rear directly upon the axle B; but between thefront ends of the bars and the axle A is interposed a spring, F, aforked brace, a, extending from the axle A to the opposite bars D, inorder to prevent the pull upon said axle from being imparted to the sidebars through the medium of the spring.

Beneath each of the bars D is arranged a spring, J, which is secured tothe under side of the bar, at or near the center of the same, andextends longitudinally throughout almost the entire length thereof.

The opposite ends of each spring are secured to the bar D through themedium of ears d, to the cross-pins cl of which the ends of the spring Jare hung, rubber springs 0 being interposed between the ends of saidspring J and the upper part of the ear-pieces to prevent rattling. Thesesprings J serve to stiffen and strengthen the bars D longitudinally andprevent them from being bent out of shape; but at the same time thesprings do not interfere materially with the free vertical movement ofthe bars, this movement being controlled to a great extent by the frontspring, F, so that the proper elasticity of the frame as a Whole ispreserved.

I do not desire to claim, broadly, the combination of the side bar of awagon with a longitudinal spring; but

I claim as my invention The combination of the longitudinal side bars,D, of a backboard-wagon, said bars extending continuously from axle toaxle, with the longitudinal bracing-springs J, rigidly secured to saidside bars, D, at the center and at each end, all substantially as andfor the purpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

CHARLES LE GRAND.
